“Anyhow, Corbett was here about that time. I have seen the secretary to the company that owns these flats. Corbett took the rooms for six months from September first. When asked for references he gave his sister’s name, and as she banks with the National—and she has always paid her rent for five years—it was good enough. Still, I must confess that Corbett could hardly be in Wyoming in October if he lived here in September and in November.”
The barrister answered between his set teeth: “Yes, it is rather puzzling.”
“Perhaps the letter was left there as a plant.”
“An elaborate one. It must have been conceived a month before the murder.”
“But suppose it never came from Wyoming. We have no proof that it was written in America.”
“We have proof of nothing at present.”
“Well, Mr. Bruce, have you a theory? This is the place where you ought to shine, you know.”
“I have no theory. I must think for hours, for days, before I see my way clear.”
“Clear to what, sir.”
“To telling you how, when, and where to arrest the murderer of Lady Dyke.”
